The time dependency of specific material properties can be considered in the OpenBridge Designer analysis. In RM Bridge, these time dependencies are defined by sets of variables. The default database has sets of variables for creep, shrinkage, and relaxation definitions that are prepared for each property group. For example, by country, and by each considered Code the property group will contain one set of time-dependent functions. At RM Bridge \ Analyzer \ Properties \ Time Functions a plot of the Creep & Shrinkage variation, elasticity modulus for any defined concrete element, and relaxation for pre-stressed steel can also be viewed here. The other option, C+S calculation, activates the use of internal formulas for concrete creep and shrinkage, and steel relaxation.
